Abstract

The design and implementation of a low-frequency spectrum analyzer is described. The design features a low-cost spectrum analyzer for use in the electrical engineering senior year communications laboratory. The frequency range of the spectrum analyzer extends from under 1 Hz up to 20 kHz. It covers the spectral region of interest in speech processing and baseband data transmission, and provides the students with a flexible signal analysis tool.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
